摘　　要：随着科技的快速发展,商业化的锂离子电池在能量密度上正逐步接近其理论极限,难以跟上便携式电子设备和电动汽车对更高能量密度的迫切需求。此外,伴随着能量密度的持续提升,目前广泛应用的锂离子电池所采用的有机电解液也暴露出了易燃、易泄漏等潜在的安全隐患,这无疑给其未来的应用和发展带来了挑战。固态锂离子电池因具有高能量密度和安全性,成为当前研究的热点,固体电解质作为固态锂离子电池的核心,因其具有不可燃性、高机械性能和在抑制锂枝晶穿刺方面具有显著的潜力而备受关注。目前,固态电解质主要分为硫化物、聚合物、氧化物和卤化物固态电解质。本文综述了固态锂离子电池电解质的特征及研究进展,并展望了今后的发展趋势。With the rapid development of science and technology,commercial lithium-ion batteries are gradually approaching their theoretical limits in energy density,making it difficult to keep up with the urgent needs of portable electronic devices and electric vehicles for higher energy density.In addition,with the continuous improvement of energy density,the organic electrolyte widely used in lithium-ion batteries has also exposed potential safety hazards such as flammability and easy leakage,which undoubtedly brings challenges to its future application and development.Solid-state lithium-ion batteries have become the focus of current research due to their high energy density and safety.As the core of solid-state lithium-ion batteries,solid electrolytes have attracted much attention due to their non-flammability,high mechanical properties and significant potential in inhibiting lithium dendrite invasion.At present,solid electrolytes are mainly divided into sulfide,polymer,oxide and halide solid electrolytes.In this paper,the characteristics and research progress of solid-state lithium ion battery electrolytes are reviewed,and the future development trend is prospected.
